This is an old School Boom Box cake that I made for a friend. He was having an 80's theme party. It is a 1/2 sheet white cake with Strawberry and whipped cream filling. I covered the cake with gray fondant then used black fondant cut outs of various sizes to make the dials and knobs. If you notice the speakers have the mesh look I got that by purchasing a small amount of screen and rolling it on the fondant before I cut out the circle for the speakers.
or the dial I found an image on line and printed it on photo paper. It was the only thing on the cake not edible. I used powdered sugar which I tinted black for the background of the cake so it looked like it was lying on the street and used a bit of the same mixture with a fine pain brush to add some depth to the color of the edges of the boom box itself.
